After installing today the new google camera app from play store I noticed that it does not show as installed on play store but it was. So I decided to run uninstall all updates of the camera app with the settings. After the next reboot my phone showed me that I have to sign in to my google account (like on the first boot), so I did it. I checked the accounts on the settings menu and noticed that all accounts was cleared even my wifi settings. Now I wanted to delete this buggy camera app and restore it with a zip file, so I booted into recovery and noticed that cwm can't mount E (my SD Card).
It is the first time something like this happened to me. Do I have to be worried about my phone?
